COOLING DEVICE.

Application filed May 3, 1926.

This'inventionaims to provide a cooling device which may be employed to reduce the tBIHPBlit'flllfl of the surrounding air during hot weather. The invention may take several forms; for instance it may be constructed like a. refrigerator insomuch that it may be provided internally with shelves so that food may also be stored therein; the device may be also built and applied under the seat of an automobile so that cool air may be supplied withinthe vehicle so that traveling during hot weather may be made more comfortable. Againthe device i'nay be made in a light compact form so that it may be moved from room to room as occasion may require.

The invention is hereinater more fully described with theaid of the accompanying drawings Figure 1 is a front elevation of one form of the invention.

Figure 2 is a section on the line 2-2 of Figure 1,

Figure 3 is a section on the line 3: of

" Figure 2, and

Figure 1 is a section on the line 4-4.- of Figure 3.

Figure 5 shows a plan view of Figure 1.

Figure 6 is a sectional elevation showing the invention located under the rear seat of an automobile,

Figure 7 is a section on the line 7-7 of Figure 6, and

Figure 8 illustrates the invention in compact and portable form, and without any food storage space.

Referringmore particularly to Figures 1 to 5 0f the drawings, 1 designates a box-like structure the legs 2 of which are preferably supported on castors 3, so that the device may be moved easily from place to place. The bottom 4 of the structure is made of, or lined with, metal or some substance that will not be damaged by water, and slopes downwards from all sides to an opening 5, usually more or less centrally located. 6 in dicates perforated plates supported within the structure which are adapted to support pieces of ice 7 and above the ice food receiving raclrs 8 are provided.

Under the structure an electric motor 9 is mounted which has a bevel gear 10 on its shaft. This gear cooperates with a gear 11 on the vertical. shaft 12 which latter is mounted in bearings 13 secured to the end 14 of the structure. On the vertical shaft Serial No. 106,352.

12 are two gears 15 and 16which coact with gears 17 and 18 on shafts 19 and 20 respectively.

The shaft 19 is rotatably mounted in the ends'14 and 21 of the structure. and has a plurality of fans 22 thereon. The shaft 20 is supported at one end by the end 14 of the structure and at the other end by bearing 28 usually integral with the bearing 24%, which latter is dependingly secured to the top 25 of the structure. On the shaft 20 there is a second gear 26 which meshes with a gear 27 on the shaft 28 on which latter a discharge fan 29 is secured. The bearing 2 1 supports the shaft 28. A hinged lid 30 covers the discharge opening 31 in the top 25 when the discharge fan is not in operation. 32 indicate doors which are opened for the insertion of food or ice into the structure.

when ice has been placed on the perforated plates (3 the temperature of the air in the structure is reduced, as this occurs the ice commences to melt and the resultant water drops through the perforations in the plates and falls onto the inclined bottom 4 from which it runs through the drip opening 5 under which a vessel 33 may be placed.

The hinged lid 30 is then moved so as to expose the opening 81 and the motor 9 is put into operation. Air enters through the drip opening 5 and is thoroughly agitated by the fans 22 in that portion of the structure through which water from the melting ice is falling. The air then passes upwards around the ice through the perforations in the plates 6 not covered by the ice, is further cooled by the propinquity of the latter, and. is then discharged by the fan 29.

Referring now to Figures 6 and 7, 34 inclicates the rear wheel of an automobile to which a pulley 35 is attached, and 36 indicates a rear seat. Under the latter a boxlike structure 1 is provided, the ends 14: and 21 of which support a fan shaft 19' having fans 22 thereon. On the fan shaft 19 is a pulley 37 which is driven by a belt 38 which also passes round the pulley. Similar perforated plates 6* are supplied within the structure, and the bottom 4* slopes downwards from all sides to a drip opening 5*. A vertical shaft 12 is rotated by the fan shaft 19 through gearing 15 and 17 and an upper gear 16 on the vertical shaft cooperates with a gear 18" on the shaft 20 The latter has a second gear 26 thereon which meshes with a gear 27 on a shaft 28? on which a discharge fan 29 is also provided. It will be noted that in this form of construction the discharge opening 31 is in the front instead of at the top of the struc ture.

The primary difference between the latter construction and that shown in Figures 1 to 5 and in Figure 8 is that the rotation of one of the rear wheels of an automobile is employed for driving the fans 22 and the discharge fans 29; the driving mechanism has therefore been adapted to the changed conditions, and the discharge opening has been moved to the front of the device.

In Figure 8 the construction isthe same as in Figures 1 to 5 except that the boxlike structure is only provided with suflicient space above the perforated platesti for ice storage as the food racks shown in Figures 2 and 3 are in this case not provided.

While in the foregoing thepreferred constructions of the invent-ion have been described and shown, it is understood that the invention is susceptible to such modifications as fall within the scope of the appended claim.

In a device of the character described,

the combination of a box-like structure, a vertical shaft supported by said structure,

'means for driving said vertical shaft, perforated plates in said structure, ice on said perforated plates, a horizontal shaft extending across said structure under said plates, and driven by said vertical shaft, a plurality of fans on said horizontal shaft adapted to agitate air under said ice so that said air is cooled by contact with the drippings from the ice and by contact with the latter, the top of said structure having an opening therethrough, a discharge fan in said opening, a second horizontal. shaft driven by said vertical shaft, means for rotating said dis charge fan by the rotation of said second horizontal shaft, racks adapted to support food above said perforated plates, the bottom of said structure having an opening therethrough for the escape of drippings and for the admission of air into said structure, and means for driving said vertical shaft.
